A bit late to the party here.
Italy is the
first I've been aware of banners being used outside of North America. (Is there anywhere else?)
The standard in North America has been for every bannered route to have both a City and Abbrev. I like the idea of, for consistency's sake, expanding that to be a sitewide standard.
(Not saying there's no way in Centralia you'd convince me otherwise though.)Similarly, in itaa.csv, maybe
itaa;ITA;A18;Dir;;Diramazione per Catania;ita.a018dircat;A18Cat->
itaa;ITA;A18;Dir;Cat;Diramazione per Catania;ita.a018dircat;A18Dir,A18Cat...and the .list name would match the
route root.
--There are some cases of unique Route+Banner combinations still having a City & Abbrev, E.G ita.ss027vargig.
Consistency would dictate either losing the City & Abbrev, or adding City & Abbrev to all bannered routes. Again, I prefer the latter approach.
